THE COMPLEX TASK OF CONTROL OF ENERGY CONVERSION QUALITY IN AC ELECTRIC DRIVES

The paper considers the complex task of control of energy conversion quality in electromechanical systems, along with application of the principles developed for control of energy conversion quality in regulated AC electric drives. We also present the possibility of compensation of high-order harmonics of an electric motor’s power consumption and electromagnetic moment through control by the energy converter. The principles proposed are extended to systems with thyristor voltage regulators in the stator, systems with frequency converters including an autonomous voltage inverter with a pulse-width modulation system for AC motor drives and thyristor excitation systems for synchronous motors, as well as to search optimization systems.
